Directions (Q$$. Nos. $$1-4) These questions consists of two statements each printed as Assertion and Reason. Whileanswering these questions you are required to choose any one of the following four responses.Assertion : Degree of freedom of a monoatomic gas is always three, whether we consider vibrational effects or not.Reason : At all temperatures (low$$ or $$high), vibrational kinetic energy of an ideal gas is zero.

Question

Infinity Learn · Accepted Answer

In ideal gases, there is no $$inter-particle$$ interaction. So, no vibrational energy is there.∴ Only the kinetic energy contribute to the internal energy.Mnoatomic gas molecules have only translational kinetic energy which has three degrees of freedom .
